I am porting TIDL to DRA7xx on Linux Automotive SDK.
I aleray update opencl to 1.1.17.1
but TIDL is no work.

    TIDL is supported in Vision SDk uses cases. Not integrated with openCL

    Hi kumar.desappan

    It's a long time that we develop on linux automotive SDK . We want to power up with TIDL on Linux SDK. Could you give me some suggestion?

    Hi,

    We would be supporting TIDL in Procssor SDK Vision (Vision SDK + Linux) case from the next release onwards.

    If you have ccs connectivity, you may want to look at where the DSP has crashed. The PC address is given in the logs along with SP information.

    Thanks and Regards,

    Hi Ya Lin,

       If you have updated OpenCL on your system, you need to recompile the TIDL-API library and examples (this restriction will be removed in later OpenCL/TIDL-API releases).

    Hi Piyali

    Will the new version be released in the first half of this year?
    I have been recompile the TIDL Library and example.

    Bellow is the PC and SP information:
    pc = 0xfeb0df34, sp = 0x00802780.

    It's crash in function dsp_rpc() on monitor.c
    This function is in ocl_tidl_dsp.lib
    , but I am not able to find the source code.

    Hi Ya Lin,

        There are two possible causes for the OpenCL monitor crash in your case:

    Cause 1: Installed firmware and installed OpenCL DSP library get out of sync.  Since you updated OpenCL to 1.1.17.01 by yourself, please verify the updated OpenCL on your system.  Check that VER/SHA symbols match up.  Make sure all shipped OpenCL examples run correctly.

    Cause 2: TIDL-API and OpenCL get out of sync.  For OpenCL 1.1.17.01, the corrsponding TIDL-API version should be v1.2.2.  If you have different version, you can clone the repo and check out the corresponding tag.  Recompile TIDL-API library and examples.  Run the examples to verify that they work correctly.

    Hi Yuan

    What is the minimum requirement for the ti-ipc version?
    My current version is 3.47.

    Hi Ya Lin,

    I don't know the MINIMUM requirement. Usually, we use a specific Processor SDK version to keep various components in sync. For OpenCL 1.1.17.01 and TIDL-API 1.2.2, they were built and shipped with PSDK Linux 5.2.0.10. The ti-ipc version in PSDK 5.2.0.10 is 3.50.03.04-r0.2.0.
